Question

Which of the following is correct for the given equilibrium?

(Equilibrium bb for the reaction in water and benzene are $K_{\text {water }}$ and $K_{\text {benzene }}$ respectively)

• A. $K_{\text {water }}>K_{\text {benzene }}$
• B. $K_{\text {water }} < K_{\text {benzene }}$
• C. $K_{\text {water }}=K_{\text {benzene }}$
• D. None of these

Answer 1

Answer: (B)

In benzene, acetic acid undergoes dimerisation while in water, acetic acid remains in monomeric state, so

$K_{\text {benzene }}>K_{\text {water }}$
